Coplien and Martin Debate TDD, CDD and Professionalism

Debate sprang up at JAOO ’07 around Bob Martin’s assertion that “nowadays it is irresponsible for a developer to ship a line of code he has not executed in a unit test.” In this InfoQ video, he debated with Jim Coplien on this and other topics, including Design by Contract vs. TDD and how much up-front architecture is needed to keep a system consistent with the business domain model.
